Reconfiguring two shortest paths in a graph means modifying one shortest path to the other by changing one vertex at a time so that all the intermediate paths are also shortest paths. This problem has several natural applications, namely: (a) repaving road networks, (b) rerouting data packets...
Shortest paths cannot contain cycles. We already ruled out negative-weight cycles. If there is a positive-weight cycle we can get a shorter path by omitting
pair shortest path query problem: Given the interval model of an unweighted interval graph of n vertices, build a data structure such that each query on the shortest path (or its length) between any pair of vertices of the graph can be processed efficiently (both sequentially and in paralle...

Graph theory is one of those things in the computer science field that has the stigma of being extremely hard and near impossible to understand. My goal for this post is to introduce you to graph theory and show you one approach to finding the shortest path in a graph using Dijkstra's Al...
